Preventing AdBlue in a Diesel Tank in Galon Uchaf: Why It Happens
AdBlue already in your diesel tank? Then put this page aside a moment, leave the ignition and motor off, and call 0333 366 0103. Usually, when your engine has not run, it is emptied and fully purged where your vehicle is around Galon Uchaf. The remainder of this page covers why it happens and how to make sure it doesn't — handy if you're reading before it has happened.
AdBlue in a diesel vehicle, and its separate tank
Diesel goes to your motor — but many newer diesels driven around Galon Uchaf and Morlais Castle carry a second fluid as well. The exhaust, not the motor, is where AdBlue goes: dosed into the fumes to fresh them, from a separate tank.
Every tank has one filler of its own. Under one flap, side by side: that is the layout on many vehicles. Elsewhere, AdBlue's filler is beneath the bonnet or in your boot instead. Diesel goes in at each filling station call-out, again and again. A driver who has to stop and think where it goes normally tops up the AdBlue side, from a bottle, and much less often. It's in the gap that the error happens.
AdBlue in your diesel tank around Galon Uchaf: how it takes place
Three things tend to come together, and carelessness is rarely one of them.
Haste comes from the warning. The car tells you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up gets done in a rush, before work on a drive off Ring Road, or heading home in the car park at Martyrs Club.
Next, your hand goes for the cap it knew on the old car — because a hire car, a new motor or a company car puts the fillers somewhere your last one did not.
Nothing stops the pour after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Whether it occurs in Gurnos or the middle of Galon Uchaf, it is the same few seconds.
How to tell the AdBlue filler from the diesel one
A couple of seconds is all the checks take — so check them before you tip anything, on a drive in Pen-y-Darren or a forecourt around Galon Uchaf.
- Blue and lettering: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not its position.
- On plenty of cars, the size tells: AdBlue has the smaller filler neck.
- Check inside your fuel flap: many motors carry a label there saying which fuel goes where.
- In your boot or under the bonnet: that is where the filler sits if it's not by your diesel cap, and the handbook says which.
- Picking up a hire or company car, say at the car park outside Merthyr Tydfil? Ask whoever drove the car last before leaving, rather than when the light goes on.
Keeping AdBlue out of your diesel tank when you top up
A routine for the day the light comes on, wherever in Merthyr Tydfil that is.
- Turn off once parked — level ground, motor stopped, and not in a rush by Bryniau Road on the verge.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works.
- The two behind a single flap? Then confirm the cap on your diesel side stays shut before raising the bottle.
- Gently does it, through the bottle's own spout, till it's full or the bottle is empty.
- Close the cap and check again. Make sure the diesel cap was never opened. Only then start your car.
Stop there if you find, at step two or three, that you've already poured into the diesel side. Stage five is off limits.
Galon Uchaf: already put AdBlue in the diesel tank?
What follows is a short order of things, beginning with not starting the motor. Keep your ignition off too, because on many diesels switching it on by itself runs the fuel pump. AdBlue doesn't mix with diesel — it sinks to the bottom of that tank, where your fuel is sucked from — so do not top up with diesel to thin it.
The staff at Esso, Asda or any forecourt will usually help pushing your car away when asked. Leave it where it is if you're on your own drive around Galon Uchaf.
Already started? Stop when it's sensible, then turn off. On the M4, under 25 miles from Galon Uchaf, that means the next junction. Distance counts — a quick hop across Galon Uchaf makes a smaller job than heading under 25 miles to Newport — so say roughly how far it went.
What occurs when our technicians turn up in Galon Uchaf
Our van reaches the vehicle wherever it has come to rest — your own driveway, near Glow Uchaf Residents Centre, or by the local primary school. Both the work and the quote rest on three replies — which fluid, what quantity, and if it's run — so our technicians ask. You hear that price on the phone, before anybody heads out.
Emptying the tank comes next, then a thorough flush of the fuel system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. Your filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested. The motor is started next and tested to confirm it runs correctly, all before our engineers leave.
If your engine hasn't run, most jobs take about half an hour once we're there, using pumps that are safe on a working forecourt and quiet enough to use outside a house after dark. Your insurer will ask for an engineer's report and your VAT invoice, and both are yours once the job is done. Payment comes on the day, with no money upfront. Misfuelling cover is part of many insurance policies — so make use of the wait to check yours.
